Abstract (en)

[origin: WO9934013A1] A rapid method for determining the minimum inhibitory concentration of biocides or biocidal agents for use in anaerobically contaminated aqueous systems is disclosed. This rapid technique provides for an opportunity to determine the minimum amount of antimicrobial agents, or biocides either singularly or combination, to control anaerobic growth in aqueous streams contaminated by microorganisms. The test involves the use of pH indicator dye systems which respond to the environmental changes caused by the production of byproducts of carbohydrate metabolism by anaerobes.
